Abstract: A recoil reduction system for a firearm. In some embodiments, the recoil reduction system includes a biasing element and a butt pad assembly configured to deform substantially proportionate to each other during a recoil event. The biasing element and/or butt pad assembly may include a spring-type element or, alternatively, a dampening device. The butt pad assembly may include an open cell butt pad having a hardness that is substantially higher than conventional butt pads.

Abstract: An example charging handle comprises a body having a handle portion, a bolt engaging portion and a shaft portion extending forwardly from the handle portion to the bolt engaging portion. The handle portion of the body may have a starboard arm extending away from the shaft portion in a starboard direction and a port arm extending away from the shaft portion in a portward direction. The charging handle may comprise a grip member disposed about the handle portion of the body so that the grip member encapsulates the handle portion and the handle portion is disposed inside the grip member. The grip member may comprise a thermoplastic material overmolded on the handle portion of the body.

Abstract: A recoil reduction system for a firearm. In some embodiments, the recoil reduction includes buffer tube housed within a buttstock, and a deformable structure for setting a clearance tolerance between the buffer tube and the buttstock to reduce lateral play while enabling smooth translation therebetween. In some embodiments, a guide pin and/or skid projections provide interference between the sliding components of the recoil reduction system when in a battery configuration, while releasing the interference during a recoil event.

Abstract: A stock for a firearm. In some embodiments, the stock is configured for bi-directional folding to either side of a receiver of the firearm. In some embodiments, the stock is configured for length adjustment. A biasing element is provided for the length adjustment that biases a proximal (butt) subassembly of the stock against the shoulder of the user. The user can adjust the length of the stock by moving his or her shoulder fore and aft against the butt of the stock. The bi-directional folding and the shoulder length adjustment aspects may be incorporated into a single embodiment.

Abstract: A one-handed activation device includes a hand attachment assembly having an activatable device attachment portion securable to at least a portion of a user's hand and a first switch portion securable to at least a portion of one of a proximal phalanx of a user's thumb and a middle phalanx of a user's finger. The one-handed activation device further includes an activatable device configured to be selectively activated that is secured to the activatable device attachment portion and a first switch configured to selectively activate the activatable device. The first switch is secured to the first switch portion and it is positioned such that the first switch substantially overlies an extensor surface of one of the proximal phalanx of the user's thumb and the middle phalanx of the user's finger.

Abstract: Present novel and non-trivial apparatus and method for generating low latency position information from position signals transmitted in a narrow bandwidth channel of a radio frequency are disclosed. An aircraft (i.e., ownship) and each target (e.g., aircraft) of a time-division multiple access (“TDMA”) network receives its respective position derived from its individual source such as a satellite navigation system. A processing module of a communication device installed in ownship and each target generate position signals, and during the allocated time slots of an interface protocol, exchange position information with the others in the network over a narrow bandwidth channel (e.g., bandwidths of 25 KHz or less) of a radio frequency in the VHF range or lower UHF range. The interface protocol may also be comprised of a voice contention time slot for the transmission of messages and an order wire for the administration of the network.

Abstract: Present novel and non-trivial optical, laser-based measuring systems and method are disclosed. An optical, laser-based, or LIDAR measuring apparatus is comprised of a radiation receiver/transmitter, a beam-forming optical element, a beam steering device comprised of a deviation optical element and at least one actuator used to steer the deviation optical element in response to drive signal(s) from a processor.

Abstract: An illuminated hand cover assembly (100) is provided. The assembly includes a hand cover (102) including an index finger portion (112a), the index finger portion adapted to cover at least a portion of a user's index finger (132). A first light source (114) having a first light emission area (118) coupled to a lateral side of the index finger portion such that the first light emission area is disposed adjacent a lateral side of a middle phalanx bone (138) of the index finger. The hand cover may include a thumb portion (112b) adapted to cover at least a portion of the user's thumb (142). A second light source (116) having a second light emission area (120) may be coupled to the thumb portion such that the second light emission area is disposed adjacent a lateral side of a proximal phalanx bone (148) of the thumb.
